DOCTOR-VIBRATING DEVICE FOR PAPER-MACHINES.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed July 1, 1916. Serial No. 107,056.

To all whom it may concern:

Be it known that I, ALBERT H. KUNZEL- MAN, a citizen of the United States, residing at Chillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Doctor-Vibrating Devices for Paper-Ma-chines; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in paper making machines, and has for its primary object to provide a novel. and efficient device for vibrating the doctor back and forth over the press roll of a paper making machine.

With this and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a fragmentary end elevation of a paper machine of the ordinary construction, illustrating the improved vibrating device applied thereto,

Fig. 2 represents a side elevation of the vibrating device,

Fig. 3 represents a plan view of the vibrating device,

Fig. 4 represents a detail sectional view on the line 4- 1 of Fig. 3.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a fragment of a standard of a paper making machine in which is supported the axial trunnion 6 of the upper press roll 7 The doctor 8, which is engaged at one edge with the press roll 7, is supported upon a shaft 9 rotatably and longitudinally movable in a bearing member 10. a

The improved vibrating device includes a worm 11, rigidly secured to the trunnion 6 outwardly of the standard 5. The worm 11 meshes with and is adapted to drive a gear wheel 12 non-rotatably mounted upon a shaft 13 and confined between the bifurcations 14 of a bearing member supporting one end of shaft 18, which latter extends at right angles to the shaft 9 and terminates directly under the latter. The end of the shaft 13 adjacent the shaft 9 is supported in an auxiliary bearing member 15 and is connected with an eccentric pin or screw 16 pivotally securing one end of a relatively short connecting rod 17 whereby oscillatory movement is imparted to the latter during rotation of the shaft l3.

A pair of collars 18 are rigidly secured in spaced relation upon the outer terminal of the shaft 9 by set screws 19 and confine a coupling member, designated generally by the numeral 20, which is supported upon the terminal of the shaft 9 and includes a pair of interfitting U-shaped members 21 and 22. A pin 23 is fitted in apertures formed in the leg portions of the U-shaped members 21 and 22, whereby the latter are secured in position upon the shaft 9. The pivot pin 23 is rigidly secured in position in the U-shaped members by a set screw 24c.

What I claim is:

1. The combination with a press roller and a doctor, of a shaft arranged at right angles to the press roller and the doctor, means for rotating the shaft by the press roller, an eccentric pin secured to the shaft, a connecting rod pivoted to said pin, and a coupling secured to the doctor and having the connecting rod pivoted thereto for reciprocating the doctor on the press roller.

2. The combination with a press roller and a doctor, of a .shaft arranged at right angles to the press roller and the doctor, means for rotating the shaft by the press roller, an eccentric pin secured to the shaft, a connecting rod pivoted to said pin, a coupling positioned on the doctor and having the connecting rod pivoted thereto, and a pair of relatively spaced collars secured to the doctor and disposed upon each side of the coupling for holding said coupling upon the doctor against relative movement thereto. i

3. The combination with a press roller and a doctor, of a shaft arranged at right angles to the press roller and the doctor, means for rotating the shaft by the press roller an eccentric pin secured to the shaft, U-shaped members for holding said members a connecting rod pivoted to said pin, a pair against sliding movement on the doctor. 10 of interfitting U-shaped members located In testimony whereof I afiix my signature upon the doctor, a pin carried by the leg in presence of two Witnesses.

5 portions of the U-shaped members and hav- ALBERT H. KUNZELMAN. 1

ing a connecting rod pivoted. thereto, and a Witnesses: pair of relatively spaced collars secured to the MICHAEL L DWIG, Jr. doctor and disposed upon each side of the JAMES P. ARGABRIGHT.
